(The music contains original
electronic sounds, along with samples including Richard Wagner’s
Prelude and Libestod from his opera Tristan und Isolde,
performed by the Metropolitan Opera Orchestra of New York conducted by
James Levine, Maurice Rave’s Bolero, with Claudio Abbado conducting the London Symphony
Orchestra, and Luciano Berio’s Visage
containing electronic sounds, and vocal sounds performed by Cathy
Berberian)

There are four recorded tracks, altogether. The music, I
should say, is self-explanatory.
